A new article: The genetic legacy of a global marine invader (PNAS)

Please take a look at a newly published article on the introduction of the Pacific oyster, as well as other species that were transported with it to various regions. The article is now available in the Proceedings of the National Academy of Sciences of the United States of America (PNAS).

This study was led by Professors Erik Sotka and Allan Strand of the Grice Marine Laboratory, College of Charleston, USA, and was conducted through international collaboration, including contributions from our laboratory.

Congratulations to Erik, Allan, and all the other outstanding coauthors involved!

Special Exhibition at Kagoshima City Aquarium: The World of Marine Algae

As the opening event of the special exhibition The World of Marine Algae, a workshop on making marine algae herbarium specimens was held at Kagoshima City Aquarium in Kagoshima. Twelve elementary and junior high school students attended. The students created herbarium specimens of twenty-four species of marine algae collected from various locations in Kagoshima Prefecture.

 

 

 

 

 

New article: DNA-based floristic survey of red algae (Rhodophyta) growing in the mesophotic coral ecosystems (MCEs) offshore of Tanegashima Island

 Please take a look at our latest article on the DNA-based floristic survey of red algae (Rhodophyta) in the mesophotic coral ecosystems (MCEs) offshore of Tanegashima Island, Japan. 

 

This study presents the first comprehensive catalog of red algae comprising the sublittoral marine flora (deeper than 30 m) around offshore Tanegashima Island and represents the first exhaustive molecular-assisted survey of red algal marine flora in Japan. Morphological and molecular analyses using plastid-encoded rbcL and mitochondrion-encoded cox1 genes identified a total of 129 species, including nine newly recognized in Japan.

Spring has come!

Spring has come!
As spring arrives, the time of the lowest daily low tide shifts from nighttime to daytime, making intertidal algae surveys easier to conduct on the rocky shore. Yesterday, we conducted a survey at Nishikata Beach, Satsuma-Sendai City, which faces the East China Sea. Notably, Pyropia suborbiculata, Grateloupia asiatica, and Gloiopeltis furcata were abundant on the intertidal rocks.
